Table 4-12. Example Estimate of Gross Longshore Transport Rate for Shore of Inland Sea 



(1) H^ = 



(2) f = 



(4)

significant height reduced from gage records, assumed to correspond 

 to the height obtained by visual observers 



decimal frequency of wave heights 

 = assumed shoaling-coefficient ratio. 



(5) Hj, = Z — -fH^ = 1.062ft. 



Q = 2 X 10^ Hg = 2.26 X 10^ cu.yd./yr. from Equation 4^4 

 Note that shoreward-moving waves exist only 51 percent of the time.
